Description of the input part
On the input side, the TDA7501 (see
signals to the four AD converters of the digital car radio signal processor TDA7500. The
audio signals are adjusted by the input gain stage to the internal reference signal with 2V
rms referred to 4.15V (=V33 ·1.2575). The following CODEC interface attenuates the 2V
to 0.8Vrms referred to the CODEC's reference voltage of 1.65V which allows a DC coupling
to the TDA7500.
